What is known of Arctic kelps?
Known
- Little is known of kelp in the Arctic

Past
- Trading in Alaria along Baffin Island coast

Present
- There should be other Laminariales sp.

Where are kelp in the Arctic and what drives their distribution?
- There must be kelp in the Arctic
- We don’t know what the drivers of their distributions are
- The Arctic is changing quickly so we should figure this out ASAP

Environmental conditions
Abiotic data
- NAPA (3-Oceans) model
- Model outputs supplied by the Bedford Institute of Oceanography (BIO)

- Based on the NEMO community ocean model

- Daily surface resolution
- Five day (pentad) resolution at 75 depth layers
- Tri-polar grid
- 10 to 20 km resolution

Biotic data
- Bio-ORACLE
- RWS: Still need to flesh this out Tyberghein et al. (2012) Assis et al. (2018)
